Question 5
A buffer solution is prepared in which the concentration of NH3 is 0.30 M and the concentration of 
is 0.20 M. if the equilibrium constant, Kb for NH3 equals 
, what is the pH of this solution?

is 0.20 M. if the equilibrium constant, Kb for NH3 equals , what is the pH of this solution? (log 2.7 = 0.43)
Question 6
A 20 litre container at 400 K contains CO2 (g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). The volume of the container is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of CO2 attains its maximum value, will be:
